A cellphone tower that sparked repeated objections from Devonshire residents is up and running — and, according to an industry source, is now in heavy use.

The area of Devonshire Bay had been a grey spot for Digicel users, but the announcement in 2013 of plans to add a 60-foot antenna on the wooded South Shore hillside resulted in a petition.

Residents cited unsightliness and health risks over the tower, which is a mobile facility.

There was no word last night of the next move by the environmental group BEST, which joined with objectors earlier this year.

An independent study for the Planning Department has concluded that the radio emission from the tower was 130 times lower than limits set by the Federal Communications Commission.
